I have started a project to imitate the candelabra featured in the computer game Deus Ex: Human Revolution. The candelabra looks like this: http://imgur.com/a/BUQ8D#1
I'm having some trouble implementing my project, specifically with the diffusion of light. See below for a bad representation of my plan.
I'm using frosted 38mm diameter acrylic tubes and my original plan was to insert a metal tube holding a strip of 5050 RGB LEDs. However, despite the frosting and even addition of light diffusion "gel" (plastic sheet) inside the tube, points of light are clearly visible. One possible (long-shot) solution I read was to insert clear beads in the space between the LEDs and the outer tube, which may or may not diffract the light sufficiently.
Alternatively, I could use an RGB power LED such as the one here but the viewing angle is quite wide and I'd suppose I would need an optic which I am unable to locate for this LED.
The wiring will not be hidden but will be braided and decorative so that it doesn't look out of place.
